PATENT OFFICE I SQUIRE E. NO'LES, OF SPRING VALLEY, ILLINOIS, ASSIGNOR TO THE MUNIDIE M'ANU- FACTUR-I'NG 00., OF PERU, ILLINOIS, A. CORPORATION 013 ILLINOIS OIL BURNER Application filed September 11, 1930; SerialNo. 481,256.

' mounted in a liquid tank heateror casing and: which is so constructed that a blast of air is directed downwardly upon the flame and burner so as to spread the flame,

A further object of this invention is to provide in a burner of this kind means by which the flame spreader will not become coated with carbon as in'devices at present available. 1 r A still further object of this invention is to provide in combination with a burner of this kind a baflie plate which is so; constructed as to direct the flame, and heat ventilated by the burner toward'the sides of the tank heater.

A further object of this invention is to provide a burnerjof this kind wherein the component parts thereof may be readily cast and assembled with the minimum amount of machining.

39 The above and various other objects an advantages of this invention will in part be describedand in part. be understood from the following detailed description of the present preferred embodiment, the-same bei ing illustrated in the accompanying drawing wherein there is disclosed a longitudinal sectional view of a device constructed according to the preferred embodiment of. this invention.

'Reterring to the drawing thenumeral' 10 designates generally a tank heater which is adapted to heat water or other liquid in a stock dri'nking'tank for use by the stock on a farm. i w

i A heating unit or element generally designated as 11 is mounted within the heater 10-,

the heating unit 11 being positioned in an air chamber 18 'which has an inlet .12, the

ai'r'being adapted to travel downwardly in the air chamber 13.

The burner 11 comprises a base portion 14 of suitable configuration which is provided with a concave central portion 15 and an upstanding rear wall 16. The upper edge of the wall 16 is provided with a groove 17 for rockably and adjustably receiving a damper 18, the lower edge of the damper 18 engaging the wall'16 in the groove 17 and the upper edge engaging against an inner wall of the heater 10.

The damper 18 gravitatingly engages against a side of the duct 12 and is adapted to direct the air passing downwardly through the inlet 12 and against the burner 11, the damper" 18 being adapted to direct the air tothe, bottom of the heater 10 when in forwardly inclined position as shown in full lines in the drawing and to direct the air toward the top of the burner or in lighting position when inclined rearwardly as shown in dotted line position. The heater 10 and the damper 18 are of conventional construction being generally similar in construction tothe heater shown in Patent No. 1,461,157, dated July 10, 1923, of George W. Mundie.

When the damper 18 is forwardly inclined the incoming airv will pass downwardly, to the bottom of the heater 10 and upwardly through air ducts 19 which are mounted in the base 14, the air ducts being mounted in spaced relation to each other in the base 14.

While there has been disclosed only two air ducts 19 I do not wish to be limited to this construction as ifdesired only one duct may be provided or a plurality of ducts provided, depending only upon the size of the heater. i I

' A manifold generally designed as 20 which is provided with a pair of curved intake ports 21 and a centrally disposed outlet port 22 is adapted to be mounted on thebase 14 and communicate with the intake ducts 19, so that when the air through the ducts 19, it will be directed passes upwardly downwardly on a burner generally desig- The spreader 28 comprises a coneshaped member 29 which is-held in spaced relation to the outlet port 22 by means of radial arms 30, the arms 30 being provided with notched outer end portions 31 so as toengage against the lower edge ofthe outlet duct 22 and a bolt 32 extends downwardly through the manifold '20 and is threadably mounted in the spreader 28.

The bolt 32 is adapted to hold'the spreader 28 in adjusted position on the end of the outlet duct 22.

- The lower face of the spreader 28 is prefcrably convexed as indicated at 33 and the draft of air passing upwardly through the duct 27 is adapted to strike the convex surface 23 andkeep the spreader 28 in a relatively cool condition and assist the spreader 28 in spreadingthe flame within the heater. By having theair passage 27 directed against the-central portion of the spreader 28, the flame is held away from the lower surface of the spreader 28 and therefore no carbon is permitted to collect on the lower surface of the spreader 28.

The base plate 24 is provided with an upstanding ring 34 which is positioned spaced outwardly from the bottom of the burner reservoir 23 so as to retain any oil closely adjacent the burner 23 that may overflow or run down the stepped outer surface 26 of i the burner 23. The, oil retaining reservoir 23 is provided with an axially extending aperture 35 which isadapted to be connected to a fuel supply line 36 and a regulating valve 37 is interposed in the supply line 36 between the burner 23 and the supply tank. The valve 37 being mounted within the air chamber 13 in such position as to be partially heated thereby being at the sametime also partially cooled by the incoming draft of air so that the valve 37 will be mounted in a relatively even temperature at all times. The forward edge of. the base14 is pro vided with lugs 38 which are provided with a groove 39 at the upper surface thereof for receiving a baffle plate 40, the baffle plate 40 being provided with a relatively high forward wall and with tapering side walls 41.

The side walls 41 provide wings which partially surround the manifold 20 but are positioned in spaced relation to the manifold 20 and in practice constitute extensions of the base 14 upwardly from the concave portion 15.

In the operation of this burner, the clamper plate 18 is adapted to be swung outwardly into lighting position and the valve 27 opened so as to permit the liquid fuel to flow downwardly to the oil well 23. The fuel may then be lighted and when the burner has become heated to the desired degree the damper 18 may be swung inwardly so as to cut ofl the draft of air on the top of the manifold 20 and direct the air downwardly into the air chamber 13 and upwardly through the ducts 19 in the manifold 20'and downwardly through the outlet duct The spreader 28 will force the air outwardly and in like manner the draft of air passing upwardly through the supplemental air duct 27 willco-operate with thespreader 28 so as to force the flame rising from the well 25 outwardly and downwardly'against the concave base portion 15 of the device. The flame after striking the concave portion 15 will spread outwardly and a portion of the flame with the heat will rise rearwardly and strike the forward face of the damper 18 from which point the flame and heat will be directed forwardly. The balance of the flame and heat will be directed outwardly by the baffle plate which prevents the direct passage of the flame and heat upwardly through the heater flue. I

It is, of course, understood that various changes and modifications may be. made in the details of construction and design of the above specifically described embodiment of this invention without" departin from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

What is claimed is 1. An oil burner comprising a base .having spaced passages therethrough, amanifold extending above the base and engaging in said passages, an air discharge means in said manifold above thebase, an oil well disposed below the discharge means and having a central opening to permit air to ass'upwardly in the direction of. the mani old discharge means and opposing the downward draft of air from the manifold, means for supplying oil to the well and a spreaderinterposed between the well and the discharge means and the upward draft of air from the central opening, the axis. of the spreader being coaxial with the center of the discharge means and the central opening to evenly direct the opposing air currents in an. outward direction, said air currents maintaining the flame from the oil away from the entire surface of the spreader.

2. An oil burner comprising a base having spaced passages therethrough, a manifold extending above the base and engaging in said passages, an air discharge means in said manifold above the base and directed toward the base, an oil well disposedbelow the discharge means and having a central air opening to permit the passage of air therethrough opposing the air discharged from the manifold discharge means, means for supplying oil to the well, a spreader, and means for supporting the spreader in a position coaxial with the center of the manifold discharge means and the well opening to evenly direct the opposing air currents in an outward direction, said air currents maintaining the flame from the oil in the well away from the entire surface of the spreader.

In testimony whereof I hereunto afiixmy signature. 5 SQUIRE E. N OLES.
